    摘要: The present invention aims at providing a process for economically producing mono-p-nitrobenzyl malonate while recovering the excessive malonic acid and treating the by-product. The process of the present invention for producing mono-p-nitrobenzyl malonate comprises reacting p-nitrobenzyl-alcohol with malonic acid in an organic solvent, which may contain di-p-nitrobenzyl malonate if necessary, cooling the reaction mixture thus obtained to 35.degree. to 100.degree. C., separating the malonic acid thus precipitated and treating the reaction mixture with a basic aqueous solution at 35.degree. to 80.degree. C. The di-p-nitrobenzyl malonate formed as the by-product is effectively utilized by hydrolyzing or reacting with malonic acid to thereby give mono-p-nitrobenzyl malonate.
